Formyl Peptide Receptor 1 (FPR1)

fMet-Leu-Phe receptor is a protein encoded by the FPR1 gene.Ozcelik et al. mapped the FPR1 gene to human chromosome 19 by Southern analysis of rodent/human somatic cell hybrids and use of a cDNA probe. An FPR-like gene was also identified on chromosome 19 . An FPR-like gene that mapped to chromosome 2 was found in fact to represent an interleukin 8 receptor. Bao et al. mapped the gene encoding the receptor for the chemotactic ligand FMLP to chromosome 19, using a panel of somatic cell hybrids. They identified 2 structural homologs of FPR that similarly mapped to chromosome 19. The structural homologs did not recognize the ligand FMLP, but were thought to represent chemotactic receptors. Bao et al.  referred to them as orphan receptors and symbolized the genes FPRH1 and FPRH2.
